This one really intrigued me so I asked some long time breeders about it and showed them this pic. One breeder has had tails with wavy fur like that but not all over the body, she was really excited to see it like that.
She also said it's nothing to worry about and hers that had wavy fur all their tails all went to normal fur as they matured, so essentially it changed to normal as they grew. However, with yours being all over the body she is very interested in update pics as the glider grows and honestly I would love to see them too !!
Actually there are 2 people aside from myself

Peggy is actually considering doing a scientific study on fur. She has a pair of melonistic joeys with different fur than our typical joeys.
